To all whom it may concern:

Be it known that I, HENRY IzARD, a citizen of the United States, residing at Portland, in the county of Multnornah and State of Oregon, have invented certain new and useful Improvements in Oil-Gas Generators; and I do declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to oilgas generators and more particularly to that class of generators designed to be used with the heavier and substantially non-volatile fuel oils.

The principal object of my invention is to provide a generator of this character in which the fuel oil is first vaporized and then further heated to form a gas which gas is discharged in a suitable manner and ignited to form the burner flame.

Another object of my invention isto provide a generator of this character which is so constructed that the flame will be directed most advantageously against all parts of the generator in order to insure an eflicient operation of the same.

A further object of my invention is to provide with a generator of this character, a priming pan which is so constructed as to support a generator and which is provided with means whereby a continuous flame is maintained beneath the generator so that should the flame issuing from the generator become suddenly extinguished, any gases would be instantly ignited by the flame in the priming receptacle, thereby insuring a means for preventing any explosion of the accumulated fuel gases.

A. further object of my invention is to provide a priming pan as described with which means are provided for flooding the pan so that raw oil may be burned in the priming pan in order to pro-heat the generator and may also be burned during the operation of the generator to insure the application of a greater degree of heat to the same.

To this end, my invention resides in the novel construction, combination and arrangement of partsto be more fully described and claimed and taken in connection with the accompanying drawings which form a part of this application and in wh ch:

Figure 1 is an elevation of my improved generator in assembled relation;

Fig. 2 is an elevation from another point of view thereof;

Fig. 3 is a vertical section through the line 33 of Fig. 2;

Fig. 4: is a top plan view of the generator;

I Fig. .5 is a horizontal section on the line 5-5 ofFig. 1; i V

Fig. 6 is a similar section on the line 6-6 of Fig. 1; and

Fig. 7 is a similar section on 7-7 of Fig. 1.

Fig. 8 is a horizontal section on the line 8-8 of Fig. 3. i f

Referring to the drawings in describing the line my invention in detail, it will be seen that my improved generator comprises a priming panor' receptacle 1 which 1s adapted to be sultably secured on a base in any desired manner and is constructed to act as a support for a generator 2 supported thereon. The priming pan or receptacle comprises an annular pan having a relatively large centrally located vertically extending bore therethrough and provided at the top of its inner edge 3 with a series of spaced upstand ing lugs 4. Depending from the bottom of the priming pan is a pipe or conduit 5 having a communication with a supply reservoir 6 located therebelow, which reservoir is ada lpted for connection with a fuel supply tan z. is a wick 7 in communication with the fuel stored in the reservoir 6 so as to provide ameans whereby a continual flame or pilot light may be maintained in the priming pan. Extending from. the reservoir 6 and connected to any suitable supply tank is a connecting pipe 8 provided with a control valv therein whereby the wick in the conduit 5 may be flooded to permit of the discharge of the raw fuel oil into the priming pan.

The generator 2 is provided with a circular base chamber 9 of less diameter than the diameter oi the annular priming pan and which is adapted to be supported on the upstanding lugs 4: of ,thepriming pan and is provided with a -flat bottom 10 so thatit may rest securely upon the same and in spaced relation thereabove. The base cham- Extending through the conduit 5- IOU . 9 and is provided witha centrally located vertically extending bore l l therein for a purpose to be hereinafter described. Gonnected at its ends to diametrically opposed points at the'sidesof the top of the upper chamber 12 is a diametrically extending pipe 15 which is, arched throughout its length to be disposed in spaced relation above the top of the. upperchamber 12mm which extends over the bore 14. The under side of the pipe 15 is provided with a discharge aperture 16 disposed in direct vertical 'alinement with the bore 14: located in v the chamber 12.

Extending from a suitable fuel supply tank upwardly through the centrally located bore in the priming pan is a fuel supply conduit 17 having communicationwith a fuel passage 18 in the bottom of the base chamber 9 of the generator.

In the operation of, my device, the primmgpa'n orreceptacle is'first provided with a suitable quantity of raw fuel oil by means of the flooding'of the wick disposed in the conduit 5 after which the 'oil is ignited and. will burn to pro-heat the generator, the flame from the burning oilascending along the sides'of the generator chamber owing to the greater, diameter of the annular priming-"receptacle which "will dispose the outer edges ofthepriming receptacle beyond the outer side edges of the generating chambers. l/Vhcn the oil contained in the priming receptacle has been burned out, oil will be fed through the wick 7 which I will burn and provide a continuous flame below the burner whichl designate as a pilot light. If at any timethe flame from the generator should become extinguished,-this pilot light would igni-teany gases which would collect and thereby prevent any explosion. If at any smearing the operation ofthe generator, it is desired to increasethe' heat drum intensity of the flame, it is merely necessary to open the control valve provided in' the connection 8 leading to the reservoir 6, whereby the pilot light will be 'fioodedand raw oil will be discharged into the priming receptacle and will; burn in connection with theflame? from i the gases "gener ted in the tamer;

f the. chambers of the generator have 4 W d "thefb se"chamber"where it becomes vaporbeen "siifliei'ently' pie-heated, fuel in reenter through'the' passagejlg to and ascends thi' i h the connecting i pipes td'the la'rger upper chamber 12 and 'ii'i iivhi'ch'it will expand-and become gasifie d,

continuing to ascend upwardly and passing through the arched pipe 15 of the generator. From this pipe the generated gas will discharge with considerable force downwarly through the aperture 16 located therein and downwardly through the bore located in the upper chamber and be directed against the Hat top of the base chamber where it will be caused to spread out and when properly ignited, the gases will burn at this point and mingle with the air through the air ducts formed between the upstanding lugs on the priming receptacle. Theflame 'will thus be disposed against the base chamber, against the upper chamber and in fact against all parts of'the generator so that the entire surface of the generator will be directly and positively affected by action of the flame to provide an eliicient manner of heating the generator walls, whereby to insure practically instantaneous generation not of vaporized oil but of fuel gas.

' I claim 1. A generator as described comprising a base chamber adapted for connection with a fuel. supply, an upper chamber spaced above said base chamber, an upwardly extendingcommunicating pipe securing the upper chamber to said base chamber, said upper chamber having a bore extending tlIGIQtlHOUgh and a pipe extending across said bore and in communication with said upper chamber, said pipe having an aperture therein in alinement with said bore to discharge fuel gases downwardly through said bore.

2. A generator as described comprising a base chamber adapted for connection with a fuel supply, spaced upwardly extending pipes on said chamber, a second chamber in communication therewith on the upper ends of said pipes, said second chamber having a vertically extending centrally located bore therethrough and an arched pipe over the top of said second chamber having its ends in communication therewith, said arched pipe extending above the bore in said second chamber and having an outlet therein disposed in alinement with said bore to discharge fuel gases downwardly through the bore.

3. A device of the character described comprising an annular priming receptacle provided with a bore extending therethrough, a series of spaced lugs on the inner edge of said receptacle, a fuel supply connection to said receptacle, a generator having a flat bottom to rest on said lugs to form air passages between said bottom and mner edge of the receptacle, the outer edge of saidreceptacle extending beyondthe side edges of said generator, and a fuel supply conduit for said generator extending upwardly through the'bore in the receptacle.

4. A device of the character described comprising a priming receptacle, a suitable fuel supply, a generator disposed over and spaced from said priming receptacle, a connection between said generator and said fuel supply, a wick-fed burner in said receptacle providing a continuous flame, a reservoir disposed below said priming receptacle, the lower end of said Wick extending into said reservoir, a fuel supply connected to said reservoir and means to control said last mentioned fuel supply to flood said reservoir whereby to discharge fuel into the priming receptacle.
